Application filed .Tani ary21, 1928 Serial No. 248,439.

This invention relates to'pump bleed'e rs for use in connection with lift pumps, andis designed primarily to release the volume of water contained in the casing of a lift pump, whereby the COlLlHlIIOf water in the pump casing above the frost lineina'y be released when desired ;but.it is to be'understood that a pump bleeder in accordance with this'i nvention may be used for releasing other liquids for which it is found applicable. W A

The invention has for itsobjects to provide in a manner hereinafter set forth, a pump bleeder for the purposes referred to, within convenient reach, which is self-aligning in its operation, and which will not m urethe hands by catching them between thehandle and pump casing. Further objects of the in vention are to provide a stopper in combination therewith, the contour of which will'compensate for the arc of the operating lever, and

which when seated within thecasing is capable of maintaining awater-tight. joint, without independent ten'sion 'ng devices, regard.-

' less of the vibrations of the pump.

scribed and 'illustrated'in the accompanying drawings, wherein is shownan embodiment of the invention, but it is to be understood that changes, variations and modificationcan be resorted to which fall within the scope of the claimshereunto appended. I

In the drawings wherein like reference characters denote corresponding parts throughout the several views:

Fig. 1 isra fragmentary view in side eleva-' tion of a pump casing showing the adaptation therewith of the. pump bleeder in accordance with this invention; and further, with .a cutaway portion of thepump casing in the area of the stopper. 1

Fig. 2 is a fragmentary viewin front'elevation of a pump casing showing the adaptation therewith of the pump bleeder in accordance with this invention. 1 r p A pump bleeder-in accordance with this invention-includes an angular operating lever L'wh ch is pivotally attached to'tlie'front face of a pump casing 2 by a U-sliapedbracket B.

Thebight 30f thepivot bracket is spaced with 3 respect to the front of the pump casing 2 and is circular n cross section. The sides of the bracket Bare flared and flattened as at at, so as to provide aplane surface'to conform tothe i side faces' of the pump casing 2. The flared section 4: is perforated in its center line to re- VCQIVQYSCIBWS 5, by mean-s'of which, it is secured to the. side faces of the pump casing.

The pivotedoperating lever Lis 'substan tially circular in cross-section and is angular shaped'in contour with respect to its'length. Then the lower section f the operating lever is in a'valve seated position as shown in Fig. 1, it is disposed in spaced parallel rela tion witlrrespect to the front face ofthe pump whereas the handle section 1, while in a valve seated position, is angularlydisposed therefrom- At a point where the two sections 1 and 6 of the operating lever form the obtuse angle, said sections are flared and flattened to a substantially circular section 7. The flared area 7 is perforated in closeproximity to the center thereof, as at 8", to receive the pivot support upon'which it swings.

Near the lower end, the operating lever is enclosed within a Ushaped guide member G,

which provides perfect alignment during the swinging motion. The guide member G is made of a strip of metal rectangular in cross-. section having bases 10, vertical sides 11, and a bight 13. The laterally extending bases 10 of the guide bracket conform to the front face of the pump casing, and the faces thereof are perforated in a center line to receive screws 12,'by means of which the guide bracket is se-,

cured to the pump casing. The perpendicu-,

larly extending sides 11, of the guide bracket,

are in spaced parallel relation with respect to each other, providing by the spaced inner faces thereof averticalguide. for the operating lever. Theouter ends of the sides 11 are closed at 13 toprevent the operating lever from swinging out of alignment and to space the outer end of the handle portion 1 from the pump casing when the valve is entirely open.

The lower end of the operating lever termiis perforated at its center to receive a screw 15 by means of'which the resilient frustoconical shaped stopper 16 is secured'to the nates in a flattened circular portion 14 which operating lever. The sides 17 and 18 of the stopper 16, which taper from the inner to the outer end thereof; compensate for the circular swinging path of the operating lever or any imperfections residing in the Walls ofthe seat, and provides a water-tight joint when positioned within the opening 19 of the pump casing.
